I have a vintage Craftsman Sears Best scroll saw jig saw. The Sears Best label signified that the tool was of the highest quality and the best that Craftsman offered. This saw has a auto-scroll feature where the blade shaft unlocks and it can be rotated 360 degrees. This is extremely handy when doing really tight cuts. This saw belonged to my father. I do not know if he ever used it. It is in like new condition. I have one exactly like it that I have used for years and he had to have one when he saw mine. I have really enjoyed using mine over the years but I do not need two of them.
